original application flied May 13, 19524, Serial No. 712,976. Divided and this application filed March 8, 1926. Serial No. 92,985.

This invention relates to drying machines and the subjectatter thereotl is a division troni our co-pending application tor patent, Serial Number 712,976, tiled the 13th day More specifically the substance ot the .present case4 is directed to machines adapted tor progressing rows of aligned form carriers through a drying enclosure by means of intermittently actuated endless conveyors.

rlllie primary object ot the present iinprovements is to provide a novel orm oic drying enclosure sub-divided to aiiord superposed compartments with a subjacent passage-way, whereby the drying medium is caused to traverse said enclosure with looped directional iiow.

ther objects and attendant advantages will be apparent troni the following detailed explanation ot a typical embodiment ot our invention, as illustrated in the accompanying sheets ot drawings, and succinctly detined as tofeatures oit' novelty-as well as scopeby the sub-joined claims.

in the drawings:

Fig. I is a plan View of a hosiery drying machine embodying this invention7 parte being broken away-or `in section--to more clearly illustrate certain underlying features.

Fig Il is a vertical section, taken approximately on the plane indicated bythe arrows H-H in F ig. l; and, Y

Fig. 111 is a view in elevation, at the feeding-in end of the machine, with a portion of the upper enclosing shell broken away to disclose certain underlying parts.

The machine herein illustrated and to which our invention has been, fork convenience, specifically applied, comprises a traine worlr ot standard section verticale 4t, braced by similar section transverse members 5, closedin `by therino-insulated plates 6, to atioid upper and lower compartments 7, 8, through which rows ot aligned torins 9 are intermittently progressed by endless chain conveyors 10; and an air passage 1l, by way ot' which a vertically rotatable 'fan 12, circulates the drying medium with looped directional iiow, as indicated by the arrows shownon Fig. 111. The aforesaid compartments 7,

8, and air passage 1l are conveniently, though not essentially, rectangular in transverse section, while the former if' is subdivided by spaced vertical partitions 13 with an attached diaphragm 11i. lt is also observable that the lower compartment 8 extends laterally to the front and rear ot the machine to provide boarding and stripping stations B, S, respectively, whereat operatives are located t-o apply the wet articles to be dried by progression through vthe machine, and to remove the same after dryinfr. Furthermore, the front and rear walls 15, 16, ot' the upper compartment 7, are provided `withingress and egress openings 17, 18, respectively, ot appropriate configuration to permit tree passage for the successive rows oi clothed forms 9, as will be readily understood by those acquainted with the art to which our invention appert-ains.

Laterally across the upper portion of the compartment 7 are a plurality of'radiator pipe banks 19-dividing said upperportion into parallel Zones a, b, and c-through which the heating medium is circulated in accordance with well known practice. It

is also noteworthythat the drying compartment 7 is transversely divided by a parti" tion 2O affording upper and lower chambers with communicating slots 21 for the tree passagev of the forms, 9; said partition and slots serving to deiine a looped-directional c`rculatory flow for the drying medium, as indicated by the arrows on Fig. 1H.

The endless chainconveyors 10 are threaded through the compartments 7, Sover and under sprocket wheels 22, 23, respectively;` aswell as around relatively larger front and rear chain wheels 24:, 25, as best indicatedrin'A Fig. lil. riihe means e'ective to progress the chain conveyors 10 comprises a change gear including a toothed wheel 26 associated-or integralwith .one of the sprocket kwheels 22, meshing a gear 27, on a horizontal front of the compartment 7. This second horizontal shaft 3Q, in turn, is rotated through the medium ot' an intermittent bevelcouple 34,'by a vertical shaft 35 journaled in bearings 36, and said shaft is revolved by a Worm drive 37 and belt transmission 38 troni a countershaft--not shown-connected with any convenient source ot' power. Rotation ot the tan l2 is alsoetl'ected by Va drive 39 troni the aforementioned countershal't, as will be understood by anyone acqiilaintcd with the art. It is Well to note that `the hereinbeforc referred uto sprocket wheels 22am attached on transverse shafts 40,journalcd lin bearings 4l, at the sides oi the compartment 7; whereas, the sprocket wheels 23 and .chain Wheels 24, 25 are supported by stub-shafts 42, in appropriate bearings 43, `to afford free passage tor the *iorms l9 through the machine, as later `on fully explained.

The `means for supporting and progress ing successive rows ot aligned forms 9 are fully describedin our previously referred to 'co-pending application Serial Number 712,976, and for brevity herein will be but briefly explained. Each row of aligned forms 9 `is carried by a T-section bar 44 having anti-friction end rollers 45 adapted to traverse the guide-Way tracks 46best illustrated in Fig.` II, means being provided to temporarily arrest and stabilize each successive row o-t' said forms at -the boarding station Blfas fully set` forth in the above cited application for patent.

An `exhaust outlet or outlets 47 is, or are, provided in connection with the passage 11 to carry away the proper quantity of`moisturefladen aiigvwhile an appropriate damper control `vvillobviously-be associated therein so-as -to regulate the exhaust as desired.`

w The operation Aof our novel drying machine .is`brietly-as follows y Assuming `that an operativel is `located at each station B and S, and -that motion is ftransmittedito the Worm drive 87, the verticalshafft will be rotated, and, by .means ofthe bevel-couple 34 im art intermittent rotary motion -ito the horizontal shaft 32.

In turn this shaft 32, through the ,gearsi31,

30,27and 26, will intermittently rotate `the front transversefsha'ft 40, with consequentialprogression oi the conveyor chains 10. Ifthe shaft 40 is driven in a clock-Wise direction-for example, the conveyor chains 'l0 will be traveled in the direction indicated by the arroivson Fig. VII, and as a bar 44 is temporarily arrested at the station B, the forms 9 thereon will be clothed with Wet hose by the operative. The following progressive movement of the conveyor chains 10 advancesthe bar 44 of clothed forms 9 along theV guide-Way tracks `46, through the ingress opening `17, into the first drying zone a of the compartment 7, replacing them at the hosearrivcs at the egress opening iti. This intern'iittent progression ot' the rows oi Jorme 9 through the drying compartment 7 `will occupy sullicient time so that, when the forms 9 arrive at theegress opening i8, the hosiery thereon will be thoroughly dry.

Vlilith the'nent progressive movement ot the conveyor chains 10, the roiv ot dried hose is advanced tothe station il, vf'hereat the operative will strip `them from the terms 9. Attention is drawn to `the tact that each track 4h at the station hi is interrupted at 48-Figz lll-and provided with an indent 49 functional as a pivot ior the rollers 45, whereby the ilorn'is t) automatically gravi tate towards the operative stationed there atto aid stripping Upon further movement the forms are reversely rocked as indi cated at fc, within the compartment 8, as will be understood by following the travel of the conveyor chains l0 ahoutthe chain Wheels, and the course of the rollers 45 over the indented parts 5G of the trucks 46. Incidentally, it will be understood that the tracks 46 are interrupted, where necessary, to accommodate `the illustrated dight ofthe conveyor `chains l0 relative to `thetraiweil of the rollers 445 over said tracks. i

`From the foregoing it is `thoughtithat the advantages and novel features involved in our invention will be fully appreciated, `While the looped circulatory flow of the heatino medium relative to the rows of alignedJ forms 9 is so apparent as not to require further explanation herein.` y

'Having thus described our invention, `We claim i l. vA drying machine for textile articles including an Aenclosure .having Lopposed lat` eral lower extensions, said enclosure being subdivided by .a `transverse slotted partition to attord 4upper and ,lower communicating compartments with `the base thereof defining a sub-passaUe-ivay connecting the extensions", means subdividing `the upper compartment into parallel drying zones, and means for circulating a drying medium through `the upper andback through the lower compartments with looped directional how.
